To aZZ whom, it may concern: v

Be it known that we, DUDLEY D. SPRAGUE, of California, Moniteau county, Missouri, and PEARLEY J. SPRAGUE, of Higbee, Randolph county, Missouri, have invented a certain new and useful Improvement in Straw-Stackers for Thrashing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying -drawings, forming part of this specification, in which- Figure 1 is a top View of the attachment and the rear or-back end of a thrashing-machine, and Fig. 2 is a side elevation of same. Fig. 3 is an enlarged top view of the track, intermediate carrier, and the rear end of the stacker. Fig. 4 is a vertical longitudinal section taken on line 4 4, Fig. 3. Fig. 5 is a transverse vertical section taken on line 5 5, Fig. 3. Fig. 6 is an enlarged detail view, illustrating the crank for agitating the intermediate carrier;

and Fig. 7 is an enlarged detail View of one I of the raddle-belts.

Our invention relates to a folding-stacker attachment for thrashing-machines; and our invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the 0 rear end of a thrashing-machine; B, a derrick secured to the top of the machine by hinges B, so that it can befolded down ontop of the machine when not in use; 0, a rope connected to the stacker by means of a suitable bail, G,

D, a pulley swiveled to the upper portion of the derrick, and over which the rope 0 passes, and

E a Windlass journaled in suitable boxes, E,

secured to the top of the machine, and around which the rope G is wound to raise the stacker. In these parts, per sc, we claim no invention.

F represents a circular track, consisting of a ring pivotedto the upright timbers or posts A of the machine, or to an object near the machine, by means of arms F, formed upon or secured to the ring bytheir outer ends, and a rod, F passing through the uprights A and through the inner ends of the arms. (See Figs. 3 and 4.) The ring being thus pivoted to the machine, it can be lowered or raised at will,

and can be folded up against the rear end of the machine when desired. The outer portion of the ring is supported by ropes or chains G, connecting it with the top of the machine. (See Figs. 1 and 2.) Common bolts may be used instead of the rod F for connecting the arms of the track to the machine, if desired.

Suspended from the track F by means of suitable hangers, H, is a frame or turn-table,

H. The upper ends of the hangers have outwardly-turned flanges H which embrace the track. (See Figs. 4 and 5.) There are preferably four of these hangers, and as the track is circular it will be seen that the frame or table can be turned in either direction, as shown by the dotted arrows, Fig. 3.

To the outer portion of the table or frame is secured the stacker I, the connection being made by the guclgeons of the lower drum or shaft, K, of the raddle passing through straps or brackets I, secured to the sides of the stacker, and brackets J, secured to the frame or table. The stacker is thus free to be raised I and lowered by the rope and Windlass de-' scribed.

K represents the upper shaft or drum of the 7 5 raddle, journaled in the upper end of the stack er. The raddle consists of endless belts L, of

a which there are any desired number. WVe have shown three, and they are held in their proper relative positions by fitting in circumferen- 8o tial grooves of the drums or shafts, or grooved disks may be secured to the shafts to receivethem. They are provided with spikes L, as

shown, placed a suitable distance apart. The

floor of the stacker is beneath the raddle, and the straw and chaff are carried up between the floor of the stacker and the raddle-belts, as shown by the arrows in Fig. 4, passing beneath the lower shaft or drum, K, whichcompresses them, reducing their bulk. l/Ve prefer to make 0 one or more openings, M, in the floor of the stacker, (see Fig. 1,) to allow the straw and chaff to fall through at any desired point. The openings are made by having a part or parts, N, of the floor removable, and these parts or 5 sections may be held in place when the. openings are closed by straps N, secured to the low er edge of the sides of the stacker, (see Fig. 2,)

or by other suitable means.

The space between the table and stacker is 2 stone 1 closed by an apron, 0, preferably secured to the front cross-piece of the frame or table, and extending up into the stacker the desired distance. 'lVe prefer to make this apron of sheet metal, and we secure strips 1? to the frame or table, with runner-shaped forward ends, which bear upon the apron, holding it always in the proper and same position relative to the shaft or drum K, whatever may be the inclination of the stacker. The apron does not in the least interfere with the vertical movement of the stacker, nor does the movement of the stacker interfere with it.

Q represents an intermediate carrier, onto which the straw, &c., is first discharged from the machine, and by which it is carried back to the raddle, which takes it up the stacker. The carrier has a solid bottom, and has sides Q and notched boards Q for moving the straw, c. Secured to the rear ends of its sides are plates or strips Q which assist in guiding the straw, 850., onto the apron. (See Fig. 4..) The rear end of the carrier rests on the table or frame, and the forward end is supported 011 a shaft, R, bent to form a crank, R, (see Fig. 6,) to which it is secured by suitable boxes, B The shaft is secured to the frame by boxes R, and is connected by an arm or pitman, It, with a wrist-pin, S, on a beltpulley, S, on the outer end of a shaft, S se cured to the frame by suitable boxes, S, and having a bevel-wheel, T, secured to its inner end, which engages with a similar wheel, T, on the upper end of a vertical shaft, T journaled in a suitable box, T, by which it is secured to the frame or turn-table, and on the lower end of which is a belt-pulley, T, which receives power from the machine. (See Fig. 4.) The belt-pulley S connects with a similar pulley, K, on the raddle shaft or drum K. The pulley I) should be directly over the center of the track F, and the vertical shaft T directly beneath the center of the track, so that the turning of the table does not increase or decrease the distance of the shaft from the machine. Through means of the described gearing, power is had to operate the raddlebelts and agitate the intermediate carrier.

U represents a U shaped strap tying the rear end of the frame or table together, and to this strap the rear hanger, H, may be secured.

V represents a curtain or hood, made from suitable cloth, secured by its upper edge to the top of the machine, (see Figs. 1 and 2,) and by its sides to the uprights A or other part of the machine, and its lower edge is secured to a hoop, V, connected to the arms of the track F by pins V The object of the hood is to prevent the machine from blowing the straw and chaff (and to protect the same from side winds) too far back, so that it would not fall through the track onto the carrier. It (the hood) can be folded upthat is, the outer part of the hoop can be raised until it comes against the top of the machine-either by hand, or it may be raised or folded by the carrier as the latter is folded.-
